How do I average column values from a tab-separated data file, ignoring a header row and the left column?

问题 My task is to compute averages from the following data file, titled Lab1_table.txt : retrovirus genome gag pol env HIV-1 9181 1503 3006 2571 FIV 9474 1353 2993 2571 KoRV 8431 1566 3384 1980 GaLV 8088 1563 3498 2058 PERV 8072 1560 3621 1532 I have to write a script that will open and read this file, read each line by splitting the contents into an array and computer the average of the numerical values ( genome , gag , pol , env ), and write to a new file the average from each of the

Does “use strict” in the constructor extend to prototype methods?

女生的网名这么多〃 提交于 2019-11-28 08:03:37
问题 I'm trying to figure out whether the definition of 'use strict' extends to the prototype methods of the constructor. Example: var MyNamespace = MyNamespace || {}; MyNamespace.Page = function() { "use strict"; }; MyNamespace.Page.prototype = { fetch : function() { // do I need to use "use strict" here again? } }; According to Mozilla you can use it as: function strict(){ "use strict"; function nested() { return "And so am I!"; } return "Hi! I'm a strict mode function! " + nested(); } Does it

“use strict”; now allows duplicated properties?

问题 I just found that in the last Chrome 42 and FF 37.0.2 this lines of code are perfectly legal "use strict"; var o = { p: 1, p: 2 }; (copy-pasted from MDN ) In IE 10-11 and Opera 28.0.1750 it throws error as expected. In the same time, abc=0; causes error (undeclared variable) as expected. Does anybody know what caused such change? 回答1: There is a Bugzilla ticket here. From what I gather (here and other pages I have looked up), duplicate properties are legal in ECMAScript version 6, opposed to

Uncaught SyntaxError: In strict mode code, functions can only be declared at top level or immediately within another function

Hello when I run this project in Developer mode (grunt server) https://github.com/kennethlynne/generator-angular-xl everything is ok but when I run it in production mode (grunt build) I get an ` Uncaught SyntaxError: In strict mode code, functions can only be declared at top level or immediately within another function Anyone have any idea what's going on? Thanks, Ps. I posted a link to the project instead of code since the JS is split in many files. Bergi It's just what the error message says: functions can only be declared at top level or immediately within another function You must not put

'caller' and 'arguments' are restricted function properties and cannot be accessed in this context

孤人 提交于 2019-11-27 23:26:25
问题 I am trying to create a simple debugging function that simply shows the caller of a function, like this: function xe() { console.log(xe.caller().name) } With this I would just be able to add xe() to a function and it will log the calls to the function– just a short, simple addition to help with debugging. Debugging sugar, so to speak. Unfortunately I get the error from the subject-line: TypeError: 'caller' and 'arguments' are restricted function properties and cannot be accessed in this

Is there a good *strict* date parser for Java?

吃可爱长大的小学妹 提交于 2019-11-27 23:00:30
Is there a good, strict date parser for Java? I have access to Joda-Time but I have yet to see this option. I found the "Is there a good date parser for Java" question, and while this is related it is sort of the opposite. Whereas that question was asking for a lenient, more fuzzy-logic and prone to human error parser, I would like a strict parser. For example, with both JodaTime (as far as I can tell) and simpleDateFormat, if you have a format "MM/dd/yyyy": parse this: 40/40/4353 This becomes a valid date. I want a parser that knows that 40 is an invalid month and date. Surely some

Get current function name in strict mode

柔情痞子 提交于 2019-11-27 15:55:57
问题 I need the current function name as a string to log to our log facility. But arguments.callee.name only works in loose mode. How to get the function name under "use strict" ? 回答1: For logging/debugging purposes, you can create a new Error object in the logger and inspect its .stack property, e.g. function logIt(message) { var stack = new Error().stack, caller = stack.split('\n')[2].trim(); console.log(caller + ":" + message); } function a(b) { b() } a(function xyz() { logIt('hello'); }); 回答2:

How to turn off MySQL strict mode in Rails

狂风中的少年 提交于 2019-11-27 13:06:35
问题 Upgrading to Rails 4, it seems MySQL strict mode is now on by default for Rails connections. I say this because my Rails app is getting "Mysql2::Error: Data too long for column" when saving a string value longer than 255 characters. Yet, I paste the same query into MySQL console (where global strict mode is reported to be off) and it works fine, just with truncation warnings. As further evidence, it says here "Rails 4 both use strict mode by default". My question is how can I turn strict mode

Would this enable “use strict” globally?

非 Y 不嫁゛ 提交于 2019-11-27 12:49:37
问题 Similar, but not the same as, How to enable ECMAScript "use strict" globally? I have bought JavaScript Patterns and it recommends enabling use strict. Adding it to the two dozen javascript files would be a bit of a chore, so enabling it globally would be nice. I originally thought about adding to the top of my main.js like this: "use strict" require({ priority: ["jquery", "raphael", "myapp"] }); However I then thought that it maybe would only enable it for that file. I then thought about this

Strict Violation using this keyword and revealing module pattern

Having trouble getting the following to pass jslint/jshint /*jshint strict: true */ var myModule = (function() { "use strict"; var privVar = true, pubVar = false; function privFn() { return this.test; // -> Strict violation. } function pubFn() { this.test = 'public'; // -> Strict violation. privFn.call(this); // -> Strict violation. } return { pubVar: pubVar, pubFn: pubFn }; }()); myModule.pubFn(); I understand it's being caused by the use of this in a function declaration, but I read something Crockford wrote and he said the violation is meant to prevent global variable pollution - but the
